Specification of I.etters Patent.

' Patented Aug. 19,1 91 3.

Application filed January 23, 1913. Serial No. 743,821.

To all whom it may concern Be it known? that I, LAns W. SODERBERG, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in /Vrenches, of which the following is a specification.

The object of this invention is to construct a wrench in which the movable jaw of the wrench may be adjusted or tightened upon the article being gripped by revolving the end portion of the handle of the wrench, the feeding being by screwthread, and also to provide means engaging said screw-thread which may be disengaged therefrom allowing the movable jaw.

to be moved quickly to any degree of openmg.

In the accompanying drawings. Figure 1 is a. longitudinal View looking at the face of the wrench, a portion of the screw-catch being broken away. Fig. 2 is a longitu- '(lllltll scctlon through the wrench on the line 2-.2 of Fig. 1. F i 3 is a fragmentary sectional view of the handle showing the catch disengaged from the screw. Fig. 4 is a section through the movable jaw, on the line 44. of Fig. 2. Fig. 5 is a transverse section on the line 5-5 of Fig. 2. Fig.

G is a transverse section on the line 6-6 of Fig. 1.

The wrench. bodyis formed of a circular tubular handle portion 7, a square neck portion 8 having the elongated opening 9, and a T-shaped head 10 formed with the square portion forming the rigid square and pipe jaws.

A rod 11 is rotatable within the wrench body, has its central portion formed with screw-threads as at 12, and has a circumferential groove 13 cut near its outer end.

The movable jaw having the pipe jaw lat has a reduced portion 15 which fits within the opening 9 and has the side pieces 16 riveted to the reduced portion, thereby forming the lower member of square jaw and also holding the movable jaw in place allowing it to slide longitudinally in the opening. A pin 17 carried rigidly in the movable jaw, lies in engagement with said groove 13, thus forming a connection be-.

tween the jawand rod 11 whereby the rod may be rotated and at the same'tirne move the jaw.

The tubular and rotatable handle portion 18 telescopes the lower portion of the handle.

and has a closed end 19 having an aperture therein into which the square end 90 of rod 11 is rigidly held by the headed bolt 21.

A catch member 22 having a toothed segment portion 23 projecting through the opening 24 in the circular handle portion and engaging the teeth of the screw-tln-ead 12, is held yieldingly in said engagement by the two flat springs secured to the Wrench body 1, the free ends of the springs engaging the catch member. The catch member is formed with incut sides 96 to facilitate the raising of said member by hand. I

With the catch in engagement with the screw-thread the handle portion 18 may be turned thus rotating the rod 11 and feeding the movable jaw, this method of adjustment being used when but a slight tightening is required. By raising the catch free from the screw-threads the rod 11 may be moved freely by the handle portion 18 thus moving the jaw to any desired position, when the catch is dropped into engagement again with the screw-thread and the. wrench fur ther tightened by the turning of handle 18.

It w1ll be seen that with a wrench of thisdesign very rapid adjustments can be made and furthermore when the wrench is adj usted to grip its object it can be further tightened to secure a positive grip. It will also be noted that both adjustments are made by the handle 18, the quick adjustmentbeing the longitudinal movement thereof with the catch disengaged and the other adjustment being the screw feed by revolving said handle.

I claim as my invention.

1. A wrench comprising a body having a rigid jaw, a rotatable rod slidable longitudinally of the body and formed with a screw-threaded portion, a movable jaw having connection with said rotatable rod, a movable toothedseginent, and spring members connecting the body and toothed segment at longitudinal ends of said toothed segment for holding said toot-bed segment normally into engagement with said threaded portion of the rod, and said adapted when said toothed-segment is disengaged from the rod, to allow the rod to be moved freely longitudinally.

In testimony whereof I have hereunto set 5 my hand in presence of two subscribing Wittudinally within the body portion and formed with a screw-threaded portion, a, movable jaw having connection with the end of the rod nearest the rigid jaw, a toothed-segment in engagement With said screw-threaded portion and adapted to be nesses.

disenga 'ed therefrom and a cylindrical handle ivortion telescobing the end of the LABS SODERBER'G' tubular body portion being fixedly eon- Witnesses:

nected to said rod, said handle adapted when rotated, to feed SalCl rod longitudinally and Gopies of. this patent may be obtained for five cents each, by addreseing the Commissioner of Patents.
